Wideband Channel Estimation for Hybrid Beamforming Millimeter Wave Communication Systems with Low-Resolution ADCs

Millimeter wave (mmWave) communications is a promising technology to increase data rates to users.  In mmWave communications, large antenna arrays are needed to form directional beams to overcome the high pathloss. Power consumption becomes a significant challenge.  By reducing the number of RF chains and adapting the analog-to-digital converter (ADC) resolution in each RF chain, power consumption can be dramatically lowered.
